Sontex Supercal 531
Heat and cooling energy calculator for energy, power, flow, volume and high and low temperature.
The Sontex Supercal 531 is an energy calculator that measures heating and cooling energy, power, flow and temperatures, alone or combined with a Superstatic 440 or 449 heat meter, for example for greenhouse heat deliveries. This Modbus RTU template reads energy, power, flow, temperatures, volume, set day and monthly values and error flags, and lets you set date, time, set days and the module address from ModbusCloud.

Send your device list
If a device is not in the library yet, we build the template for free as soon as we have the register data.
Use cases
- Show heat power, flow and high and low temperature of each calculator on a dashboard, for example per CHP unit, boiler or district heating connection.
- Keep a year of energy and volume history to compare heat use per day and month per greenhouse section or heating circuit.
- Get an email alert when an error flag such as temperature sensor 1, temperature sensor 2 or flow switches on, so a sensor fault is noticed quickly.
- Set an alarm when the temperature difference or the power drops below a threshold you choose, to spot a heat source that delivers too little.
- Read the set day and monthly values remotely and download them as CSV for your own heat delivery reports.
- Correct the calculator date and time or change the set days remotely, without opening the meter.
Installation
Disconnect the power supply of the Supercal 531, separate the cover from the housing and place the Modbus module in a free module slot. The calculator needs firmware 3.7 or higher.
Supply the module with 12 VDC from a power supply module with two outputs (230 VAC or 24 VAC) or from an isolated external 12 VDC, 150 mA supply.
Wire D1 (+), D0 (-) and Common to the RS485 port of the ModbusCloud Gateway with shielded twisted pair, shield to earth at one point. On the last module of the bus, set DIP switch S1 to 0-0-1 for the 120 Ohm termination.
Leave DIP switch S2 at 1-1-1 for 19200 baud. Every module answers on address 1 with 8 data bits, even parity and 1 stop bit, so give each calculator its own address before you connect several.
In ModbusCloud, add a Modbus device with protocol RTU, that address and 19200 8E1, import this template and compare Energy Totalizer Heating and High Temperature with the display.
Things to watch for
The module does not answer. What should I check?
Check that the module gets its 12 VDC and that DIP switch S2 is not on 1-1-0, which switches Modbus off. The default is 19200 baud, 8 data bits, even parity, 1 stop bit, address 1. Without traffic the voltage from D1 to D0 must be above 0 V. If it is negative, swap D1 and D0. Terminate only the two ends of the bus.
Energy and temperatures show huge or tiny numbers. Why?
The module sends 32-bit values with the low word first, and the template reads them that way. If you add registers yourself, set them to low word first (CDAB) as well. Read with the high word first, a temperature of 13.57 °C turns into a meaningless number. Compare High Temperature with the display to check.
Why do energy, power and volume have no unit?
The calculator reports them in the unit it is configured for. Read Energy Unit, Power Unit and Volume Unit once: 19 = kWh, 146 = MWh, 126 = MJ, 226 = GJ, 47 = W, 48 = kW, 80 = m³. Enter that unit on the registers in ModbusCloud. The Long registers are integers. Divide them by 10 to the power of the matching Decimals register, so with Decimals 3 set scale 0.001.
Can I change the address or parity from ModbusCloud?
The registers are writable, but the module expects one write that starts at Password Communication with 1234, followed by Modbus Address and Parity. It then restarts and stays silent for up to a minute. Do not power it down for 90 to 120 seconds. If one write per register is refused, use the Sontex Prog531 or Prog449 software. Writing is off per gateway by default, so request it for the gateway first.
What are the ST1, ST2 and monthly values?
ST1 and ST2 are the values the calculator stored on set day 1 and set day 2. Last Set-Day1 and Last Set-Day2 give the month and day of that storage, Set-Day1 and Set-Day2 the next set days. The monthly registers hold 32 stored monthly values per counter, numbered 0 to 31, and Last Monthly Data Day gives the day of the month on which they are stored.
